Generally, the prime concern for concrete for structural engineers has been its resistance to mechanical stress, i.e. strength. In recent years, durability has emerged as equally important. However, durability cannot be achieved with reducing the W/C ratio, high compressive strength, more cement, air-entraining admixtures or corrosion inhibitors alone. To achieve concrete durability in critical environments, properties like […]

Question: Is Penetron slurry applied on the negative side or the positive side of a concrete structure? Answer: PENETRON SLURRY can be applied on either side of the concrete structure. It will depend on the practicality and the most cost effective method of applying the slurry. Question: How far can Penetron slurry penetrate inside concrete? Answer: Penetron […]

EPDM is a type of synthetic rubber Its two primary ingredients, ethylene and propylene, are derived from oil and natural gas. EPDM rubber foam sheet manufacturers produce gaskets, seals and many other custom die cut parts in EPDM elastomers for customers that span across industry groups and international locations. Applications Used in the proper environment […]

On paper, achieving a complete waterproofed structure seems like an easy job to achieve accomplish. In fact, that is why many contractors do the waterproofing themselves. However, the following information can be used to help achieve a water-tight structure: Drainage – providing a means of removing water that enters. Drying – allowing moisture to be […]

Climate change is seemingly constantly in the news lately. Even the Pope talked about it during his visit to Kenya recently. So, the big question is: how should new/existing developments cope with climate change-related issues? In recent years, various buildings and developments in Nairobi have been focused on going green: that is reducing energy consumption, […]

WHY INTEGRAL CRYSTALLINE WATERPROOFING TECHNOLOGY Integral waterproofing is also referred to as internal waterproofing. This type of waterproofing functions within the pores of the concrete as applied to on the surface. Integral waterproofing chemicals are designed either to penetrate into the concrete once applied from the surface of the concrete or mixed into the concrete during batching. Integral […]

Expansion joints are also called movement joints or isolation joints. In buildings expansion joints allow for the concrete to move freely as it shrinks, expands or vibrates, thus preventing uncontrolled cracking. Buildings move due to :expansion and contraction caused by changes in temperature Swaying caused by wind seismic events/earthquakes Ground movement and vibration […]

Rising damp in buildings occurs when water from the ground rises up through the stone, block or brick wall and sometimes through the concrete floor slab by a process termed as capillarity. In simpler words, water rises up the walls of a building in the same way oil rises up through a wick of a […]

Mold Warning Signs Molds are very problematic to most home owners. When presented with the right conditions, they can grow literally anywhere in the house as long as the surface is wet or damp. This includes behind walls, under your carpet, etc. When excessive moisture accumulates in buildings or homes, mold growth will often occur, […]

Many pitched roofs are given little or no thought to their maintenance until they develop leakage problems. Very so often, the tell tale signs of a leakage problem is a wet or damp patch appearing on the ceiling. Occasionally, this may appear at certain times, for instance, after a heavy down pour. Finding a roof […]
